New anomaly observed in ¹²C supports the existence and the vector character of the hypothetical X17 boson

NUCLEAR REACTIONS ¹¹B(p, e⁺e^-), E=1.5-2.5 MeV; measured electron and positrons, energy-sum spectra and angular correlation; deduced anomalous excess of e⁺e_- pairs around 155-160null from the decay of 17.2 MeV J=1_- state in ¹²C via E1 transition. Extracted X17 boson branching ratio, mass of X17 particle; likely the same as X17 particle suggested by 2016Kr01 (Phys. Rev. Lett. 116, 042501). Scintillation detectors and double-sided silicon strip detectors (DSSD) at 2 MV Tandetron accelerator of ATOMKI (Debrecen, Hungary).

New anomaly observed in ⁴He supports the existence of the hypothetical X17 particle

NUCLEAR REACTIONS ³H(p, e⁺e^-)⁴He, E=510, 610, 900 keV; measured electron and positrons, energy-sum spectra and angular correlation of e⁺e^- pairs using scintillation detectors and double-sided silicon strip detectors (DSSD) at the 2-MV Tandetron accelerator of ATOMKI, Debrecen; deduced anomalous excess of e⁺e^- pairs around 115°, interpreted as creation and subsequent decay of a light particle during the direct capture process; extracted internal pair creation coefficient (IPCC), X17 boson branching ratio, mass of X17 particle with confidence level; likely the same as X17 particle suggested by 2016Kr01 (Phys. Rev. Lett. 116, 042501). ⁷Li(p, e⁺e^-)⁸Be, E=441 keV; measured angular correlation of e⁺e^- pairs for the 17.6-MeV, M1 transition in ⁸Be as a test of the experimental apparatus and methodology.

On the X(17) Light-particle Candidate Observed in Nuclear Transitions

NUCLEAR REACTIONS ⁷Li, ³H(p, γ) E=450, 900, 1100 keV; measured reaction products, Eβ, Iβ, Eγ, Iγ; deduced total energy spectrum and angular correlation of the electron-positron pairs from transitions in ⁸Be and ⁴He, invariant mass distribution, branching ratio, neutral isoscalar particle mass.
